4. Operating Instructions
The AC Infinity Fan Speed Controller features a simple rotary knob for operation.
- Turning On/Off: Rotate the knob fully counter-clockwise until you hear a click to turn the fan OFF. Rotate clockwise to turn the fan ON.
- Adjusting Speed: Once the fan is on, continue rotating the knob clockwise to increase the fan speed and airflow. Rotate counter-clockwise to decrease the fan speed and reduce noise levels.
- Speed Settings:
- "L" (Low Speed): For minimal noise and reduced airflow.
- "M" (Medium Speed): Suitable for most general applications, balancing airflow and noise.
- "H" (High Speed): Provides maximum airflow for situations requiring strong ventilation.
